When the ping is received, the recipient must send back a pong as soon as possible. wsproto is a WebSocket protocol stack written to be as flexible as possible. To that end it is written in pure Python and performs no I/O of its own. Instead it relies on the user to provide a bridge between it and whichever I/O mechanism is in use, allowing it to be used in single-threaded, multi-threaded or event-driven code.
